Posted on October 31, 2022 Do smoke detectors ever look old? The plastic that they come with, as well as the life expectancy, can start to show that it’s nearing its end when you see some yellow coloration on your smoke detector or carbon detector. If you notice any of these symptoms, it is time to replace your carbon or smoke detector. Smith Pink Trucks can help you not only replace these worn-out units, but also ensure that your wiring and installation is impeccable. #smokedetector #electricalservice #fireprotection
